Jim is it possible to just buy the case and fittings if we already own the hoses and VCR's?

Great video btw, maybe more guys will get interested in doing things the proper way.

I just ordered my 1/2" hoses and the guys at the supply house thought i was crazy for it.

I just installed a 410 system with 50' of 7/8-3/8" line set and pulled down to 250 in 10 minutes with a rise to 300 after 20 minutes using 3/8" hoses straight to the pump.
Cant wait to see how it does with the 1/2" hoses

If you're already using multiple 3/8" hoses any time saved will be spent rasslin' the thicker 1/2" hose IMO

Not to rain on the parade here, but even though it looks like a lot of cool toys, and it would be a nice set up to use on large systems.......

Well it just looks like about 15 min of work hauling and setting up. Some of the stuff would be cool to have on the average job, but the rest seems like overkill to pump out a small unit like that. I do like the core tool and I use mine often, but not for pulling vacuum, I will try that next time. The micron gauge is nice as well. But those hoses look like a PIA to work with. However I have not had a chance to try them, so I can't say too much.

I r the king of the world!...or at least I get to stand on the roof and look down on the rest of yall

It is really not hard, nor does it take a long time. The video, beginning to end is 10 minutes, I really did not skip filming any of the steps. The hardest part was getting the core tools on the valves because of the close proximity of the service ports of that brand of unit. I assembled the kit to make it easy. The hoses are Appion hoses and are very flexible for 1/2" hoses. The 6' length makes the whole thing easy to set up and manage. The case makes it easy to gab everything in one neat package and carry it wherever you go.

Believe me, it makes the job go so much faster that you would find yourself using the same tools if you had to service a window air conditioner.

Nice vid/setup. I just installed one of those units thursday,it was a dry swap out instead of a comp. I'm glad that's not my brand, pain in the but. Hopefully I will be ordering some of these tools soon,but I need to save up a few more pennies yet.

The 6' Appion 1/2" hoses are as flexible as the 5' 3/8" black yellowjackets I have but they are harder to manage in most situations because they weight twice as much. Plus the two 3/8 on my pump pulls the full 7 cfm through the 1/4" connections.

1) Would it not be better, less leak chances, to have the hoses connect to the pump with a brass connection, like a tee or manifold(tree not not gauge)?

2) you did release the nitrogen before attaching the had gauge, correct? I thought I heard something like "I do not want to expose the BluVac to these pressures".

3) at the end you closed the CRT ball valves and released the liquid side service valve to put a positive pressure in the lines to keep air from getting in due to it being in a vacuum, correct? If yes, then do all the hose ends that are not low loss allow air in or were you just being extra cautious, why ruin all that work?

I pretty much have this setup and it is totally worth the investment! I have the appion crts and they rock, have the appion hoses 1/4" to 3/8", connect them to a yellow jacket vacuum tree and I'm all set up. Used it today, and immediately knew there was a leak, wouldn't pull down past 17000. Also have the blu-vac, totally worth it, you can watch exactly whats happening, that accurate. Helper brazed outside and left a leak on the ll side. Fixed the leak and immediately pulled down to about 170 microns and held about 250. Never been so sure about having a leak free system before I picked this up, so happy I did!

1) We did use a tee, and it is better when you only have two points that need connected like in residential work. If this was for commercial, (over 10 tons) the Appion Megaflow kit would be a better pick. Typically on larger systems you can also connect at the receiver, discharge line, suction service port and possibly other places.

2) I released the nitrogen down to about 1-2 psi so air and moisture could not work its way back into the system. When I cracked open the core tools I was making sure that I did not overload the pump. The reason I mentioned pressure is a lot of other vacuum gauges are not pressure rated. BluVac is, and it will not be contaminated if used properly.

3) At the end, I cracked the suction service valve slowly to allow the refrigerant to pressurize the system before removing the vacuum gauge. No air can get into the system, only refrigerant can leak out at this point when making connections. Before you would charge the system, you would need to purge your manifold hoses. Many a system is contaminated by poor service practices.
